I'm dealing with a condition-case construct that has more than one
handler and I need some way to indicate (outside the construct) when any
one of the errors has occurred. I could, for example, set a flag in
each handler:
(some-error
(setq flag t)
...some stuff ...)
(another-error
(setq flag t)
...different stuff...)
Is there a better way to do this?

How about:
(let (noerror)
(condition-case ...
(progn
...
(setq noerror t))
(some-error ...)
(other-error ...))
...)

Good idea, but it messes with the return value of the condition-case
body. I thought there might be some built-in method for handling this,
but I'm thinking not.

I didn't know its value mattered, but you can just use prog1...
